Hello, I was able to reproduce a kernel panic on one of my -stable machines. I tested with current and the issue does not cause the machine to drop to ddb.
When I set my vio0 interface manually to the same address that would be generated with inet6 autoconf and then manually do ifconfig vio0 inet6 autoconf to get the router, it creates an identical inet6 address on vio0. Then ifconfig vio0 -inet6 cause's the kernel to panic and drop to ddb. I have a screen shot of the ddb info below: https://github.com/jimchoffman/inet6-bug-report/blob/master/Untitled.jpg Thanks, Jim
